| * DESCRIPTION: Install a handler for all OpRegions of a given SpaceId. |
| * |
| * NOTE: This function should only be called after AcpiEnableSubsystem has |
| * been called. This is because any _REG methods associated with the Space ID |
| * are executed here, and these methods can only be safely executed after |
| * the default handlers have been installed and the hardware has been |
| * initialized (via AcpiEnableSubsystem.) |

| /* |
| * For the default SpaceIDs, (the IDs for which there are default region handlers |
| * installed) Only execute the _REG methods if the global initialization _REG |
| * methods have already been run (via AcpiInitializeObjects). In other words, |
| * we will defer the execution of the _REG methods for these SpaceIDs until |
| * execution of AcpiInitializeObjects. This is done because we need the handlers |
| * for the default spaces (mem/io/pci/table) to be installed before we can run |
| * any control methods (or _REG methods). There is known BIOS code that depends |
| * on this. |
| * |
| * For all other SpaceIDs, we can safely execute the _REG methods immediately. |
| * This means that for IDs like EmbeddedController, this function should be called |
| * only after AcpiEnableSubsystem has been called. |
